ULYSSES8'S PROFILE

Okay so I can get games to load up in windowed mode, but once I attempt switching to fullscreen I get a black screen which goes away then takes me to my desktop. The only way to go back to windowed is to restart the game or spam F4 when in the black screen. I can't get any of my games to play in fullscreen(including this new game, off, I downloaded). I've searched the internet head to toe for answers but found none. Hoping this will help, Thanks.
